big mistake updating to 2.2

ever since I updated to 2.2, no matter what rom I'm using..performance has been so poor compared to 2.1. I wish I never updated. My battery runs out quick, temperature goes up to 100F even when idle and my phone hangs every time I turn on wifi. Hopefully I find out a solution soon, i've been flashing and uninstalling roms all day these past two days. I love the phone though don't get me wrong =\

That sounds quite odd.
Are you using an unmodified SBF, or are you using a release where the author/publisher has made a lot of changes? When having problems, it may be best to stick to one release and try to narrow down your problems, instead of trying many different releases and introducing new variables into the mix.
Are you overclocking your phone - perhaps it's causing the rise in temperature? Or are you running a lot of widgets? There may be some widgets that use the system too aggressively, causing too much strain/heat.

Hi! Did you do "wipe" before and after flashing?

That is very odd. I am on Froyo and performance has been phenomenal ever since the flash.
I agree with naenee, check the ROM you're flashing...

i flashed the UK 3.4.2-117 and right now using Pay's 2.1 rom. I remember that I did wipe data/cache before flashing and after flashing. IDK, im just not having problem's with this particular rom..it seems like it happens on all the other ones im trying. I get random freezes and especially when I toggle on wifi. I recently installed setVEL and will see if battery improves, this means i don't need milestone right? I'm also using setCPU.
I might try to flash 3.4.2_131-003 PL version. Will it cause any trouble and can I go back down to UK 3.4.2-117?

Seeing as it uses the same kernel, you should be able to do so...

I have been using the orange 2.2 for several days and no specific problem is noted.

well I reinstalled pays rom first and everything is working good. No more hang ups or freezes but I still can't get the battery to last as long.My phone is mostly idled, running on 2G, just one widget, and everything in settings turned down to the least minimal settings..im talking about battery saver, screen brightness all the way down..everything off! 6 hours in and im already on 70%. I can live with that but I'm using setVsel and I know it could do better. Anyone know another way I can make my battery last longer?

I'm running Pays latest rom based on the UK 3.4.2 and it runs great. I'm also using setvsel (as every defy user should) and optimized all my vsels ([email protected], [email protected], [email protected]) using stability test. I haven't had a 'normal' day of use yet, but with heavy use (installing apps, web browsing, flashing rom) I've gotten at least a full day (~15 hrs) out of a charge.
I recommend minimizing your vsels using setvsel, then judging your battery life. Check out the setvsel thread for more help.

And remember this is a smart phone, some people report getting 2 to 3 days of use out of it. That's basically idle time tho. These new smart phones are just that, and use much more battery than the Dumbphone.

Even if that's the case (and I dispute it, I use my phone a fair amount in the ~3 days the battery averages), it still doesn't explain why the OP's phone is dropping 30% in 6 hours while idling.

When I updated to froyo, my battery life went from about 15 hours of use to 21 hours between charges. So I'm thinking the op has an app doing the draining.

Unfortunately, this is a characteristic of Android.... Ridiculously inconsistent in the battery department.

Wife's phone is on official froyo, has been amazing since updated (a few weeks ago) but since yesterday some weird reason it's been super glitchy and freezing up. Not sure why...haven't changed anything to it and she's only downloaded an app or two (such as pandora) in the last couple days...I was playing around with it trying to figure out what was up...can't figure it out. I went into titanium backup to freeze some apps thinking maybe some blur crap was freezing it up but TB froze up so I can't even get in there. Also, same as OP, the battery has been heating up really quick lately, especially when on wifi.
Not sure what's up here...but I'm hoping nothing serious! Will keep you all updated on this...we'll see if there is a trend going on here.

check your cpu usage... if it's constantly arround 99%, you may experience the "usb-plug/unplug"-bug.
try enabling usb debug and restart your phone.

I would rather say it is a characteristic of people using android, to have widely different usage patterns, causing differences in how long a charge lasts for each.

Hi there. Have you tried to recalibrate the battery? There is an app on the marke called Battery Calibrator. From what I understand if you play with roms the battery can give you problems so it need to be calibrated again. I hope this can help.

For those interested... I'm having a problem, I don't know yet if it's a bug or a hardware defect.
My phones wastes A LOT of battery while it should be suspended.
I've tracked the problem to, apparently, Motorola's SIM driver. From what I've discovered so far, the SIM isn't accepting the suspend state and therefore the "suspend" process uses too much CPU time... all of this when the phone is, supposedly, saving battery.
As I can't get a motorola engineer involved, I can't say for sure if this is the true cause... but it's the closer I've got to a diagnostic, so far.
Your problem might or not be related to this, but if you're interested about what I've found or what my kernel log looks like so you can compare with your own problem... this is the thread at motorola's owner forum:

[Q] Anyone considering returning the E4GT due to bad battery life?

I am one of the unfortunate souls who is experiencing terrible battery life due to the AndroidOS bug. I feel like I spend half my waking hours trying to figure out what is causing it and doing different things to my phone improve my battery life.
I'm definitely getting sick of it and while I realize that Samsung/Sprint may eventually come out with a software update that fixes the problem, I'm not sure I'm willing to wait since it could take months (and the issue was supposedly fixed for GS2 phones in 2.3.4).
At this point, I'm considering going back to the Moto Photon--it's battery life is simply amazing. My only issue with the Moto is its unusable camera.
Anyone else getting as frustrated as I am and considering jumping ship to another phone?

What have you done to fix it?
Are you saying that you still have the bug even aftera factory reset ?

Why not just take it back and have them give you a new one since you obviously have a defective phone?
Also how many hours are you actually getting out of the battery?
I don't see any other phone worth switching to and I have had them all. Each with their own specific problem. But this one here is as good as it gets

I've tried just about everything that has been mentioned in the AndroidOS/battery life thread (reset, wifi, autosync) but I'm still getting only 12 hours of battery life on a good day, 8 hours on a bad day
I might try exchanging the phone, but I'm hesitant to do so due to the LOS bug (I have not experienced this with my phone as of yet).
Honestly, while I love the phone in many other ways, I'm about to throw the thing out the window since 8 hours of battery life is simply not acceptable to me

Exchange it bro. Ive had two of these phones so far and none had this problem. I'm getting like 24-30 hours battery with like 4-5 hours screen on time. This phone had awesome battery. Download an apps called better battery stats. This will show wakelocks and processes that are draining the battery. Good luck man.

On a good day, the display is on for less than 30-45 min. On a bad day, the phone display time is somewhere between 90-120 minutes.

I pulled 16 hours ojt of my battery yesterday with over 12 on wifi and i was at 40 percent. I have to use wifi at work as i have no signal and when i do get signal its roaming. I would say that my conditions at work are far from ideal but this phone is great. My old phone would die before 1130(evo shift).

return it.
mine doesn't seem to get the android os bug unless i'm on a custom kernel. 1 week stock, no problems, 3 days on custom problems each day, back to stock + root and no problems for 48 hrs.
i still have to be 100% sure that my phone didn't like the kernel though so another test will be coming up after a few more days of observation.

I had the issue with the stock kernel and custom kernels. I'm just going to hold out until we can get a AOSP build and hope that using as little of Samsung's code fixes it.

I'm on stock and have nothing out of the ordinary installed. Out of curiosity, do you have a google account with full sync turned on?

Lol 8 12 hours isn't bad with a stock battery and 4.5 inch screen. If you are in a poor reception area it could be that. Otherwise you have alot of Apps running in the background.
My advice : root it and extended battery.

I average 15-20 hours easily on a charge, with a full sync google account
Everything Sync'd Listed below:

If anything else can be Sync'd I have not run across it. I also have my Tapatalk set to notify me of PM's, and updates to Subscribed topics, I removed the accuweather widget because it only updates every 3 hours and installed Weatherbug Elite and set it to update every 30 minutes. On top of all that I browse the web regularly to visit sites that are websense'd at work, and I play dungeon hunter 2, and asphalt 6 on my lunch break. At home the phone sits on my desk until its time to pass out, only used for my Rift Mobile authenticator.

This is a real bug, with android
the system/0 process goes crazy and chews up the battery.
I get about 12 hours with everything disabled (other than gmail sync) and suspend/0 chews up battery

it's a gingerbread issue, if you haven't experienced on the galaxy, you will soon
I'm also considering returning this great phone with crappy software until google releases a version of android that works.
by that time there may be a new "best android phone"

Why does the bug seem to affect the gs2 more than other phones? For example, I've never seen it mentioned on the photon forums

i use my phone a lot while im at school throughout the day , i last using wifi and 3g, and if needed i can do a quick charge while i study in the car but i lasted to 60% using 3g for a few hours

ics and battery life

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.

Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Rooting takes 5 seconds. Follow the sticky. Use odin.

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.

I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

[Q] Cyanogenmod 10 battery life on normal usage.

Hi guys,
I recently switched to CM 10 (Android 4.1.2) and the battery life is significantly lower than what I had on the stock ROM and the new Sense UI... I guess.
My phone won't run longer than 10-15 hours a day with normal usage, which means Wi-fi and 3G always on, screen on automatic brightness being used for about 1 hour in total (for one charge). However Android OS, Cell Standby and Phone Idle still account for the most battery usage, which I find weird. I have no wakelocks and my device goes to deep sleep when not used.
Is this normal behavior with the new Cyanogenmod and Jellybean or are my expectations too high? I already read most threads concerning battery life, but most of them discuss problems such as wakelocks or similar issues. My question relates to the normal behavior of CM 10.
I am grateful for all replies on the matter or personal experiences.

It's known that CM10 battery life is worse than stock JB. You can try different kernels and different governors, but it's a trade-off between life and performance.

I don't understand, I thought that CM is stripped out of unnecessary background processes and apps. As long as I'm not using any CPU or GPU intensive apps like games it should consume less battery than the stock ROM. Is there something I'm missing?

Maybe the updated kernel and drivers give better power effeciency. When the JB kernel source is released, hopefully CM10 and other AOSP ROMs will also improve.

You were saying about on screen time?

CM 10 really uses a lot of battery but of you could switch off wifi and 3g when not using, and clearing all the apps frequently in the recent menu may help... My battery then lasts from about the start of the day till night though the batterys now quite old.

That's pretty much my battery life as well. Regarding age, I'm really concerned, as I'm not able to open the phone and just replace it. But I guess that much better smartphones will come along before I consider getting a new battery and it won't be worth it any more.

I get that sometimes as well. I pick up the phone a couple of times and the battery is always at, say, 50%. Then, a couple of hours later I read a message and it suddenly jumps to 41 or lower. But from what I've read that's normal and no cause of concern.

I heard what causes the CM10 to have such an awful battery life is something that was supposed to save power when you lock your phone [Which is normally quiet often] and actually causes it to depelt, so it obvoiusly doesn't affect screen time
CM10 is a horrible ROM, get something else... I used LiquidSmooth for a while, it's a great ROM
Now running ParanoidAndroid 2.53
Btw, Stock ROM had a wonderful battery life, I only realize that now ... lots of ROMs can't reach that much

That's exactly what I did, flashed the old RUU and installed all updates. I don't know how the guys from HTC managed to do it, but the battery life on Android 4.1.1 and Sense 4+ is AMAZING. I easily get 24 hours with normal usage, over 2 days if I'm really careful.

This is what I got during a night sleep with cm 10.
I installed it yesterday so its kinda new tot me. What causes this?

Probably some nasty wakelocks. Install with wipe/factory reset if you didn't so already. Then try betterbatterystats (search xda) to find out what is causing wakelocks.

Hi all, I found an awesome way to actually get solid battery life on my galaxy nexus last night so I thought I'd share with everyone:
So theres about a bazillion threads about people only getting 10-14 hrs of battery life on the Galaxy Nexus, and it looks like alot of them have to do with "Phone Idle" just draining the battery. Lately I'd pretty much given up and just figured that 14 hrs with normal use was about all I was gonna get.
Fast forward to last night, I was using Titanium Backup to go through and delete some of the Verizon crapware that comes on the stock ROM. I deleted "My Verizon Mobile" and "VZ Backup Assistant" and then left it fully charged over night to see what would happen. Woke up this morning and my battery was at 90% after 8.5hrs! Been using it lightly today and currently I'm at 58% battery after 17hrs.
So obviously one of these 2 applications has been running in the background and keeping my phone from going into deep sleep. Super glad to finally have this figured out!
BTW I'm running rooted stock 4.1.1. Also attached a few screenshots of the battery stats:

good find man. most roms already leave those apps out so i think you just got lucky because i still see pretty terrible battery. i suggest trying out a custom rom and kernel and youll get even better battery life. btw try to shoot for a high screen on time because thats when battery life really counts.

Phone Idle and Cell Standby higher than Screen... Of course you'll be getting good battery life if you never use the phone. Screen on time is the only good measure of battery life.

Probably a majority of users here don't have those apps because they have installed custom firmware. But AOSP has the same problem.. First thing I do after flashing gapps is "disable" all the Play apps (books, magazines, videos, movies, currents, etc).

Yup, this is why we Root & ROM. There are MANY Verizon apps/services that run whether you want them or not, and that is completely bogus. It's no wonder that we love phones that can be unlocked.

I agree that screen on time is the best measure of battery life. The best I ever have gotten is three hours of screen on time. That was done using WiFi all day and screen at lowest brightness setting.
